Application filed March 3,1905. Serial No. 248,233. I

T 0 all whom it may concern? Be it known that I, EDWIN E. SLIoK, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Mill for. Rolling Irregular Shapes, of which the following is a full, clear, and exact description, refer ence being bad to the accompanying draw ings, forming which Figure 1 is a plan view of my improved mill; 2, 3 and/l are diagrammatic side elevations showing the lines of feed in the successive directions; Fig. 5 is a partial front elevation of the roughing rolls: Fig. 6 is a similar view of the edging'rolls; Fig. 7 is a partial front elevation of the third set of rolls; and Figs. 8 and 9 illustrate the passes in the finishing and bending rolls.

My invention relates to the rolling of irregular shapes such as angles, channels, beams, rails, etc., and the object of the invention is to provide a simple and compact arrangement of rolls which will give a large output without the use of laterally or sidewise moving tables, or the necessityfor laterally moving the metal sidewifie on the tables, except for the roughing TO 5;.

)art of this s )ecification in l v i In the drawings, 2 represents a continuous heating furnace in which the billets or blooms are heated and shoved out onto the vertically-movable table 3 for the three-high roughing rolls 4, ,5 and 6. A vertically-in vable table/7 is also placed on the other side of this three-high mill, and it will be understood that these tables may be either tilting or vertically-moving tables. On this roughing set of rolls the metal is'preferably given three passes as shown in Fig. 5.

.111 the form shown where I have illustrated the mill as arranged for rolling angles, a represents the metal passing through the first open pass between the middle roll 5 and the lower roll 6. The rear table 7 is then lifted with the metal upon it and the metal is shifted sidewise on the table and passed back as shown at band received on the front table 3 which. is in lifted position. The front table is then lowered and the metal shifted sidewise and passed forward from the third pass as shown at c, this pass beginning the formation of the ridge to form the corner of the angle. 1 preferabl emplo' the adjustable guides 8 by which the lengt of the two legs may be adjusted as desired.- The metal passing In this pass Where angles are rolled,

pass 71, the metal feeds over through this thirdpass of the roughing rolls is received on the rear table 7 in its lower position, and then feeds forwardly over the conveyor table 9 to the two-high set of rolls 10 and 11 shown in Fig.6. These rolls contain edging passes, the metal being shown at d. These edging passes are of different height and set the width of the blank. The metal is turned in passing from the first three-high set to the edging set of rolls, so thatit enters the edging rolls in a plane at right angles to that of the first or roughing set. After passing through one of the passes of the edging rolls, the metal feeds forwardlyon the upwardly-inclined feed-table 12 to the three-high set of rolls, 13, 14 and 15,

shown in Fig. 7. The metal passes throu h a pass between the upper and middle r0 is as shown at c, Fig. 7, and in the case of angles the adjustable side guides 16 and 17 are used to maintain the length of the legs in accordance with the point of the rldge. After passing through this pass, the metal drops down upon the feed table 18 and feeds back through a pass between the middle'and lower rolls as shown at f, Fig. 7, this pass also having adjustable side guides. The table or trough 18 is preferably inclined downwardlyv toward the rolls. The metal passing back through this three-high set enters a feedtable or trough 19 which extends at an angle to the feed-table 12. from the three-high mill into this trough 19 is bent slightly, and will also be bent somewhat in entering the three-high set of rolls 20, 21 and 22.

I have shown the table 19 as inclined upwardly as well as sidewise, so that the metal enters the upper pass and is bent in feeding in. The metal passes through as shown at g, Fig. 8, and drops upon a table or support 23 where it is moved sldewise and feeds back through the lower finishing pass shown at h, Fig. 8. This pass not only reduces the metal, but bends the legs somewhat out of the flat plane in which they have previously been rolled' After passing back through the the trough or 'eed table 24 to the final set of two-high rolls 2'5 and 26 containing the open passes, the metal feeds through one of these bending asses as shown at k by which the lient 'to its final form, and thence feeds for ward on the tabief27, to hot bed 34.

In the form shown the three-high rolls,

4, 5 and 6 are inendwise alinement with the The metal in passing angle is rolls 20, 21 and 22, and both are driven from the same set of pinions 28 actuated from the engine 29. The three-high set of rolls 13, 14 and 15 are shown as in line with the twohigh rolls 25 and 26, both sets being driven from the pinions 3O actuated by engine 31.

- set of three-high rolls may, however, be out of line with the edging rolls, giving the feedtable 12 a sidewise inclination and reducing the angle of the trough or feed-table 19. The first set of three-high rolls may be out of endwise alinement with the three-high set 20, 21 and 22, and the bending rolls may be out of alinement with the three-high set 13, 1.4 and 15, though I prefer the arrangement shown. The first pass in the third or fourth sets may be between the middle and bottom.

rolls, and the back pass between the middle and top rolls.

The advantages ofmy invention result from the peculiar arrangement of the mills whereby a compact easily operated mill is provided. The use of laterally or sidewise moving tables is avoided, and no movable tables are needed except for the roughing rolls. The metal is not carried sidewise on the laterally moving table to transfer it from one of rolls to another out of line therewith as the inclined trough between the third and fourth sets of rolls avoids this. A large output may be obtained at low expense.

It will be noted that after the metal has led forwardly from the roughing set of rolls,

there no transfer bodily sidewise of the metal 111 parallel lines. In feeding the metal forward through an upper pass of either of the succeeding three-high rolls and then back through a lower one out of vertical alinemen l. therewith, the end of the metal is merely moved laterally into line with the next pass without moving thewhole piece bodily sidewise.

The set of edging rolls may be omitted, and *n'any other variations may be made in the form and arrangement of the mills without departing from my invention.
